IMPROVEMENT IN VALVES.

Specification forming part of Letters Patent No. 216,720, dated June 24,1879; application filed May 1, 1879.

To all whom it may concern:

Be it known that I, LUDWIG BRANDEIS, of Brooklyn, Kings county, NewYork, have invented an Improved Valve, of which the following is aspecification.

The object of my invention is a valve adapted specially forwater-closets, and constructed, as fully described hereinafter, so as topermit an unobstructed flow of water, close automatically when pressureis removed, secure an absolute contact of the valve with its seathoweverfoul the water may be, and capable of bein g readily repaired should itget out of order, and easily cleaned.

In the drawings forming part of this specification, Figure 1 is asectional plan of my improved valve; Fig. 2, a sectional elevation.

A represents the casin g, of any suitable form, provided with a cap andst-ufling -hox, through which extends a spindle, B, which maybe rotatedby means of a suitable handle.

The spindle B carries an arm or gate, a,' having an elastic pad, 0, ofleather or other suitable material upon one face, and so arranged thatsaid pad may be brought squarely against the end of an outlet-tube, 0,extending from the outside and projecting some distance into the casing.

Against the rear face of the gate a bears a strong spring, 8, which hasits bearing at the other end against a screw-plug, D, adapted to athreaded socket in the casing. I

By turning the spindle B in the direction of its arrow, Fig. 1, thevalve is wholly removed from its seat on the end of the outlet-pipe O,leaving the latter unobstructed, and the water passing in through thepipe can flow freely from the casing.

On removing the pressure applied to the spindle B, the spring 8 forcesthe valve or gate firmly against its seat and effectually preventsl'urther flow.

In ordinary valves the outlet-passage leads directly from the side ofthe chamber, and any moss or other matter carried by the water is apttolodge upon the valve-seat, so that the gate cannot fit tightly, leavingroom for the passage of the water, which is thus wasted.

In the above-described valve the outlet-tube 0 projects at an angle tothe case into the chamber beyond the inner side of the case, so that anymatter carried by the water, however foul, accumulates in the chamberinstead of lodging upon the seat.

As the gate is at an angle to the spindle B, a slight movement of saidspindle will throw the gate wide open, and by turning the screwplug Dany desired pressure may be brought upon the spring and upon the valve.

I elaim-- t y The combination of the casing A, spindle B, carrying thegate a, spring 8, and outlet-tube U, extending into the case andaffording a seat for the gateyas set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

LUDWIG BRANDEIS.
